Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a rechargeable battery suitable for an electric stapler and an electric stapler having the same. Background Technology

[0002] Laparoscopic electric anastomosis devices are commonly used instruments in laparoscopic surgery. They are powered by removable battery packs, driving a motor to perform the cutting and anastomosis operations. The battery packs used in electric anastomosis devices are typically designed for single use and discarded after a single surgery. At this point, the batteries usually still contain a significant amount of charge, leading to resource waste and environmental pollution. Reusable or rechargeable battery packs for electric anastomosis devices can solve these problems. Therefore, currently, electric anastomosis devices are equipped with both disposable and rechargeable battery packs.

[0003] During the use of electric staplers, monitoring the remaining battery power is crucial. Failure to promptly alert the doctor or restrict device use when the battery is low may result in power failure halfway through firing, posing a significant clinical risk. However, non-rechargeable and rechargeable battery packs differ in their cell characteristics, leading to different output characteristics and methods for estimating remaining power (hereinafter referred to as power).

[0004] For rechargeable lithium battery packs, the typical method for detecting battery level involves using a fuel gauge to calculate the battery level, then inputting the information to the mainboard of the handle via a communication interface for display. For example, the intelligent display system for an electric anastomosis device disclosed in Chinese patent application CN116473607A uses a display driver circuit board with multiple communication interfaces, electrically connected to the battery pack, display control board, pressure sensing chip, code reader, and motor sensor to detect and display the battery level. This method requires additional communication interfaces, but current electric anastomosis handles lack this functionality, and this approach would increase costs.

[0005] For disposable battery packs, the method for detecting their remaining power is typically based on voltage detection. For example, Chinese patent applications CN118557241A, CN117731414A, and CN113533973A all rely on voltage detection to estimate the remaining power. While voltage detection-based power estimation is suitable for disposable battery packs, it is not applicable to rechargeable battery packs. Therefore, this method cannot achieve compatibility with electric anastomosis device handles.

[0006] The above background information is provided only to assist in understanding the inventive concept and technical solution of this invention. It does not necessarily belong to the prior art of this application, nor does it necessarily provide technical teaching. In the absence of clear evidence that the above information was disclosed before the filing date of this application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0007] The purpose of this invention is to provide an electric anastomosis device and a power detection method that are compatible with both rechargeable and non-rechargeable batteries, and can be powered by either rechargeable or non-rechargeable batteries with reliable operation.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An electric stapler compatible with both rechargeable and non-rechargeable batteries includes an electric stapler body and a control module. The control module is disposed on the electric stapler body, and the power supply for the control module can be either a rechargeable battery or a non-rechargeable battery.

The first processor obtains the charge level of the rechargeable battery through the first fuel gauge and sends a corresponding control signal to the voltage regulator module based on the charge level, including: If the charge of the rechargeable battery is not greater than a preset first charge, the first processor outputs a first signal to the voltage regulator module. In response to receiving the first signal, the voltage regulator module controls the output voltage of the rechargeable battery to a fifth voltage, which is less than the third voltage. If the charge of the rechargeable battery is greater than a preset first charge and not greater than a preset second charge, then the first processor outputs a second signal to the voltage regulator module. In response to receiving the second signal, the voltage regulator module controls the output voltage of the rechargeable battery to a sixth voltage, which is greater than the third voltage and less than the fourth voltage. If the charge of the rechargeable battery is greater than a preset second charge, the first processor outputs a third signal to the voltage regulator module. In response to receiving the third signal, the voltage regulator module controls the output voltage of the rechargeable battery to a seventh voltage, which is greater than the fourth voltage and less than the first voltage.

[0012] Furthermore, following any one or a combination of the aforementioned technical solutions, the control module determines its current power supply type based on its input voltage, and controls the working state of the electric stapler body based on its input voltage and power supply type, further comprising: If the input voltage is not greater than a preset first voltage, the control module determines that the power supply type is a rechargeable battery, and controls the working state of the electric stapler body in the following manner: The control module obtains the power level of the rechargeable battery. If the power level is less than a preset first power level, the control module controls the electric stapler body to issue a second prompt message and / or stop the electric stapler body from working.

[0013] Furthermore, in accordance with any or a combination of the aforementioned technical solutions, the electric stapler further includes a discharge module, which is electrically connected to the control module, and the control module controls the discharge module to start or stop working. The control module is also configured to determine its current power supply type by controlling the discharge module to switch from a closed state to an open state, and if the input voltage decreases, determining that the power supply is a non-rechargeable battery.

[0014] Furthermore, following any one or a combination of the aforementioned technical solutions, when the power supply is a non-rechargeable battery, the control module's control of the working state of the electric stapler body further includes: The input voltage is monitored. If the input voltage is less than a preset eighth voltage, the control module controls the electric stapler body to issue a fourth prompt message. The eighth voltage is greater than the second voltage.

[0015] Furthermore, following any one or a combination of the aforementioned technical solutions, the control module is further configured to determine the power level of its power supply, including: If the power supply is a non-rechargeable battery, the control module calculates the charge based on the input voltage and the initial voltage of the non-rechargeable battery; and / or, If the power supply is a rechargeable battery, the control module determines the power level based on the output parameters of the rechargeable battery, the output parameters including power level data.

[0016] Furthermore, in accordance with any or a combination of the aforementioned technical solutions, the electric stapler also includes a display device, which is electrically connected to the control module. The control module determines the electrical charge and transmits it to the display device for display.

[0017] Furthermore, in accordance with any or a combination of the aforementioned technical solutions, the electric stapler further includes a prompting device, which is electrically connected to the control module. The control module controls the prompting device to emit a prompting signal, which is an acoustic signal and / or a light signal.

[0018] Furthermore, following any one or a combination of the foregoing technical solutions, the initial voltage of the non-rechargeable battery is greater than the first voltage; and / or, The initial voltage of the rechargeable battery is not greater than the first voltage.

[0019] According to another aspect of the present invention, an intelligent power detection method for an electric stapler is provided, applicable to the detection of power in both rechargeable and non-rechargeable batteries. The method includes the following steps: The input voltage of the electric stapler is detected, and the power supply type of the electric stapler is determined based on the input voltage. The power supply type includes rechargeable batteries and non-rechargeable batteries. If the input voltage is greater than a preset first voltage, then the power supply type configured in the current electric stapler is determined to be a non-rechargeable battery, and the charge of the non-rechargeable battery is determined according to the input voltage and the initial voltage of the non-rechargeable battery. If the input voltage is not greater than a preset first voltage, then the power supply type configured in the current electric stapler is determined to be a rechargeable battery, and the power capacity of the rechargeable battery is determined according to the output parameters of the rechargeable battery.

[0020] Furthermore, following any one or a combination of the aforementioned technical solutions, the method further includes determining the power supply type of the electric stapler in the following ways: A discharge module is configured to be electrically connected to the power supply, and the discharge module has a working state or a stopped working state. The system controls the discharge module to switch from a closed state to an open state. If the input voltage decreases, the power supply type is determined to be a non-rechargeable battery; otherwise, the power supply type is determined to be a rechargeable battery.

[0021] Furthermore, based on any one or a combination of the aforementioned technical solutions, the determined power supply type and / or power level can be converted into prompt information and / or display information.

[0022] The beneficial effects of the technical solution provided by this invention are as follows: a. The electric stapler provided by this invention can be compatible with both rechargeable and non-rechargeable batteries without the need for additional communication structures. It can determine whether the power supply in the electric stapler is a rechargeable or non-rechargeable battery by monitoring whether the input voltage of the control module is greater than a preset first voltage value. It is low in cost and convenient to use and manage. b. After determining the power supply type, the present invention uses judgment logic applicable to rechargeable and non-rechargeable batteries respectively to determine the state in which the battery cannot meet the working requirements of the electric stapler and controls the working state of the electric stapler and / or issues corresponding prompt information, so that the electric stapler avoids the clinical risks caused by the electric stapler failing to fire effectively due to low power or sudden power failure. c. This invention utilizes a control module to switch the discharge module from a closed state to an open state. If the input voltage decreases, it determines that the power supply is a non-rechargeable battery. This further improves the reliability of determining the current power supply type. Even if the user mistakenly uses a non-rechargeable battery that is not being used for the first time or mistakenly uses a non-rechargeable / rechargeable battery of other specifications, it can accurately determine whether the current power supply is a rechargeable or non-rechargeable battery, thereby reducing clinical risks.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0029] With the development of medical devices, the use of electric staplers is becoming increasingly widespread, and the demand for their accompanying battery packs is also increasing. Currently, the electric stapler handle is incompatible with both disposable and rechargeable battery packs, causing considerable inconvenience. While disposable battery packs offer better emergency response capabilities than rechargeable battery packs, rechargeable battery packs are superior in terms of environmental friendliness and energy efficiency. To balance emergency response with cost reduction and environmental protection, hospitals would need to purchase both electric staplers using disposable and rechargeable battery packs. This not only increases costs but also necessitates distinguishing between the electric stapler and its corresponding battery pack, making use and management inconvenient.

[0030] In view of the problems existing in the prior art, the present invention provides an electric stapler compatible with both rechargeable and non-rechargeable batteries. The power supply of the electric stapler can be either a rechargeable or non-rechargeable battery.

[0031] In one embodiment of the present invention, see Figures 1 to 5 and Figure 9The electric stapler includes a stapler body 1 and a control module. The control module is mounted on the stapler body 1. The power supply 2 of the control module can be either a rechargeable battery 22 or a non-rechargeable battery 21. The stapler body 1 is provided with a voltage input terminal 11, the non-rechargeable battery 21 is provided with a first voltage output terminal 211, and the rechargeable battery 22 is provided with a second voltage output terminal 221. Preferably, the voltage input terminal 11 can be electrically connected to the first voltage output terminal 211 and the second voltage output terminal 221 respectively. In this way, only one voltage input terminal needs to be provided on the stapler body 1, saving costs.

[0032] The control module determines its current power supply type based on its input voltage, and controls the working state of the electric stapler body based on its input voltage and power supply type, including: If the input voltage is greater than a preset first voltage, the control module determines that the power supply type is a non-rechargeable battery, and controls the working state of the electric stapler body in the following manner: The input voltage is monitored. If the input voltage is less than a preset second voltage, the control module controls the electric stapler body to issue a first prompt message and / or stop the electric stapler body from working. The second voltage is greater than the first voltage. If the input voltage is not greater than a preset first voltage, the control module determines that the power supply type is a rechargeable battery, and controls the working state of the electric stapler body in the following manner: The control module monitors the input voltage. If the input voltage is less than a preset third voltage, the control module controls the electric stapler body to issue a second prompt message and / or stop the electric stapler body from working. The third voltage is less than the first voltage.

[0033] Wherein, the output voltage of the non-rechargeable battery is less than the initial voltage of the non-rechargeable battery; the first voltage is less than the initial voltage of the non-rechargeable battery, and the first voltage is not greater than the output voltage of the non-rechargeable battery. The second voltage is not less than the output voltage of the non-rechargeable battery when its charge is insufficient to meet the working requirements of the electric stapler.

[0034] To address the issue of incompatibility between electric staplers and non-rechargeable (disposable) batteries due to their different operating characteristics and power detection methods, this application proposes an electric stapler that can be powered by either rechargeable or non-rechargeable batteries. Furthermore, the electric stapler utilizes the characteristic that the initial voltage of a non-rechargeable battery is typically higher than that of a rechargeable battery. By monitoring whether the input voltage of the control module exceeds a preset first voltage value, it determines whether the current power source within the electric stapler is a rechargeable or non-rechargeable battery, facilitating use and management. In addition, after determining the power source type, it employs separate judgment logic applicable to rechargeable and non-rechargeable batteries to determine when the battery cannot meet the operating requirements of the electric stapler, controlling the operating state of the electric stapler and / or issuing corresponding prompts. This prevents the electric stapler from ineffective firing due to low battery or sudden power outages, thus avoiding clinical risks associated with these issues.

[0035] It should be noted that for non-rechargeable batteries, their initial voltage is relatively high, and their output voltage drops as their charge decreases during operation. The input voltage is the output voltage of the non-rechargeable battery. For rechargeable batteries, an internal voltage regulator and fuel gauge are configured. Before their charge drops below a certain value (e.g., 2%), the voltage regulator stabilizes their output voltage to a target output voltage. Preferably, the target output voltage is the third voltage.

[0036] This invention proposes an electric stapler that does not require changes to the existing hardware structure of electric staplers, such as adding a communication interface, to achieve compatibility with both rechargeable and non-rechargeable batteries, resulting in low cost and easy product iteration.

[0037] In one embodiment of the present invention, the electric stapler further includes a discharge module and a prompting device, which are disposed on the main body of the electric stapler. The discharge module is electrically connected to the control module, and the control module controls the discharge module to start or stop working; the prompting device is electrically connected to the control module, and the control module controls the prompting device to emit a prompting signal, which is an audio signal and / or a light signal.

[0038] The control module is also configured to determine its current power supply type by controlling the discharge module to switch from a closed state to an open state. If the input voltage decreases, the power supply is determined to be a non-rechargeable battery. When the discharge module is open, the non-rechargeable battery generates a voltage drop when supplying power to the discharge module, while the rechargeable battery, due to its internal voltage regulator, maintains a constant output voltage. This invention utilizes this characteristic to further determine the power supply type. Even if the user mistakenly uses a non-rechargeable battery that is not being used for the first time or mistakenly uses a non-rechargeable / rechargeable battery of another specification, it can still determine whether the current power supply is a rechargeable or non-rechargeable battery.

[0039] A schematic diagram of the module of the electric stapler body is shown below. Figure 5 As shown, the electric stapler body includes a switching power supply, a voltage detection module, a control module, a buzzer, an LED driver module, a DC-DC circuit, a motor drive module, and a motor. The switching power supply controls whether the power supply provides power to the electric stapler body; the voltage detection module detects the input voltage and transmits it to the control module. It should be noted that the voltage detection module can be set independently or as part of the control module; the DC-DC circuit converts the input voltage into the voltage required for the operation of the electric stapler body, i.e., the operating voltage of the motor drive module within the electric stapler body. The motor drive module is used to control the operating state of the motor; the control module controls the operating state of the motor drive module, the LED driver module, and the buzzer based on the input voltage, including: controlling whether the motor drive module is working, sending corresponding signals to the LED driver module to control the power indicator / LED display to show corresponding information, and controlling whether the buzzer is working.

[0040] More preferably, the electric stapler proposed in this invention will issue one or more power level warning messages before the power supply drops to a level that cannot meet the usage requirements.

[0041] In one embodiment of the present invention, when the power supply is a rechargeable battery, the control module controlling the working state of the electric stapler body further includes: monitoring the input voltage; if the input voltage is less than a preset fourth voltage, the control module controls the electric stapler body to issue a third prompt message, wherein the fourth voltage is greater than the third voltage and less than the first voltage. This embodiment differs from the prior art in that, in the prior art, the output voltage of a rechargeable battery is stabilized at a target output voltage until its charge level drops to a predetermined preset value (e.g., 5% or 10%); in this application, the output voltage of the rechargeable battery is stabilized at different target output voltages depending on the charge level range before its charge level drops to a predetermined preset value (e.g., 2% or 5%).

[0042] When the power supply is a non-rechargeable battery, the control module controls the working state of the electric stapler body by further monitoring the input voltage. If the input voltage is less than a preset eighth voltage, the control module controls the electric stapler body to issue a fourth prompt message, wherein the eighth voltage is greater than the second voltage.

[0043] In one specific embodiment of the present invention, such as Figures 9 to 11 As shown, the first voltage is 11V, the second voltage is 11.2V, the third voltage is 8V, the fourth voltage is 9.5V, the fifth voltage is 7V, the sixth voltage is 9V, the seventh voltage is 10.5V, the eighth voltage is 11.5V, the first battery level is 10% (a battery level below 10% indicates insufficient power), and the second battery level is 20% (a battery level between 10% and 20% indicates insufficient power, and a battery level above 20% indicates sufficient power). The first and second warning signals are the same, indicating that the battery is depleted through a red light and a buzzer; the third and fourth warning signals are the same, indicating that the battery is low through a yellow light; a fifth warning signal indicating sufficient power is also included, indicated by a green power indicator light.

[0044] The electric stapler performs a self-test after each startup, and then checks the input voltage. If the input voltage is not greater than 11.0V, the current power supply type is determined to be a rechargeable battery; if the input voltage is greater than 11.0V, the current power supply type is determined to be a non-rechargeable battery.

[0045] like Figure 9 and Figure 10As shown, after determining that the power supply type is a rechargeable battery, the first step is to check whether the battery's health status is abnormal. This usually involves checking whether the battery's output voltage falls within the target range. If it does, the battery's health status is normal.

[0046] The module block diagram of the rechargeable battery in this embodiment is as follows: Figure 6 As shown, the rechargeable battery includes a first processor, a voltage regulator module, and a first fuel gauge. The voltage regulator module is configured to control the output voltage of the rechargeable battery, and the first fuel gauge is configured to determine the charge level of the rechargeable battery. The first processor is electrically connected to the voltage regulator module and the first fuel gauge, respectively. The first processor obtains the charge level of the rechargeable battery through the first fuel gauge and sends a corresponding control signal to the voltage regulator module according to the charge level.

[0047] If the rechargeable battery's charge level is not greater than a preset first charge level, the first processor outputs a first signal to the voltage regulator module. In response to receiving the first signal, the voltage regulator module controls the rechargeable battery's output voltage to a fifth voltage, which is less than the third voltage. The fact that the rechargeable battery's charge level is not greater than the first charge level indicates that the current rechargeable battery cannot meet the firing requirements of the electric stapler.

[0048] If the rechargeable battery's charge level is greater than a preset first charge level but not greater than a preset second charge level, the first processor outputs a second signal to the voltage regulator module. In response to receiving the second signal, the voltage regulator module controls the rechargeable battery's output voltage to a sixth voltage, which is greater than the third voltage and less than the fourth voltage. The fact that the rechargeable battery's charge level is greater than the first charge level but not greater than the preset second charge level indicates that the rechargeable battery can meet the firing requirements of the electric stapler, but its charge level is insufficient.

[0049] If the rechargeable battery's charge level is greater than a preset second charge level, the first processor outputs a third signal to the voltage regulator module. In response to receiving the third signal, the voltage regulator module controls the rechargeable battery's output voltage to a seventh voltage, which is greater than the fourth voltage and less than the first voltage. The fact that the rechargeable battery's charge level is greater than the preset second charge level indicates that the rechargeable battery currently meets the firing requirements of the electric stapler and has sufficient charge.

[0050] like Figure 9 and Figure 11 As shown, during the use of the rechargeable battery, the data from the internal fuel gauge of the rechargeable battery is detected, and the battery's charge level is determined based on the fuel gauge data (usually the number of uses).

[0051] When the rechargeable battery has a charge level greater than 20%, the voltage regulator module controls the output voltage of the rechargeable battery to remain constant at 10.5V. At this time, the input voltage of the electric stapler body is 10.5V, which is greater than the fourth voltage of 9.5V. The control module controls the electric stapler to work normally and issues the fifth prompt message: the power indicator light turns green.

[0052] When the rechargeable battery has a charge level of no more than 20% and greater than 10%, the voltage regulator module controls the output voltage of the rechargeable battery to remain constant at 9V. At this time, the input voltage of the electric stapler body is 9V, which is less than the fourth voltage of 9.5V and greater than the third voltage of 8V. The control module controls the electric stapler to work normally and issues the third prompt message: the power indicator light turns yellow.

[0053] When the charge of the rechargeable battery is no more than 10%, the voltage regulator module controls the output voltage of the rechargeable battery to be constant at 7V. At this time, the input voltage of the electric stapler body is 7V, which is less than the third voltage of 8V. The control module controls the electric stapler to stop working (specifically, to stop firing) and issues a second prompt message: the power indicator light turns red and the buzzer sounds.

[0054] In this embodiment, when an abnormal health condition of the battery cell is detected, the voltage regulator module controls the output voltage of the rechargeable battery to remain constant at 7V. At this time, the input voltage of the electric anastomosis device body is 7V, which is less than the third voltage of 8V. The control module controls the electric anastomosis device to stop working (specifically, to stop firing) and issues a second prompt message: the power indicator light turns red and a buzzer sounds.

[0055] The module block diagram of the non-rechargeable battery is as follows: Figure 7 As shown, the non-rechargeable battery includes a cell, a discharge MOSFET, a current detection module, a second fuel gauge, a second processor, and an LED control module. The cell of the non-rechargeable battery supplies power to the load through the discharge MOSFET. The current detection module detects the output current of the non-rechargeable battery and transmits it to the second fuel gauge. The second fuel gauge determines the output voltage of the non-rechargeable battery based on the real-time detection result detected by the current detection module, and determines the battery's remaining capacity by combining this with the battery's initial voltage. Unlike rechargeable batteries, the output voltage of the non-rechargeable battery can be used as a criterion for determining its remaining capacity.

[0056] By installing a second fuel gauge within the non-rechargeable battery, the battery's charge level can be determined and recorded. Based on the second processor and the LED control module, the battery's charge level can be displayed. The LED control module is configured to control LEDs to display different colors or control the LED display screen to show the charge level. One method is real-time display: the charge level determined by the second fuel gauge is sent to the second processor in real time. The second processor sends corresponding control signals to the LED control module based on the battery's charge level, causing the LED indicator lights to illuminate different colors according to the charge level, or controlling the LED display screen to display the charge level value. For example, similarly, a red light illuminates when the battery needs replacement (i.e., the charge level is insufficient for the electric stapler to fire), a yellow light illuminates when the charge level is sufficient but not high enough, and a green light illuminates when the charge level is high enough. Another method is... Figure 8 The battery level is displayed on demand. A button is provided on the body of the electric stapler. Only when the button is pressed, the second power meter determines the battery level of the non-rechargeable battery and sends it to the second processor. The second processor sends a corresponding control signal to the LED control module according to the battery level of the non-rechargeable battery to display the battery level.

[0057] See Figure 9 and Figure 11 During the use of the non-rechargeable battery, the output voltage of the non-rechargeable battery is detected, and the output voltage of the non-rechargeable battery is the input voltage of the electric anastomosis device body.

[0058] If the output voltage of the non-rechargeable battery is greater than the eighth voltage of 11.5V, that is, the input voltage of the electric stapler body is greater than the eighth voltage, then the control module controls the electric stapler to work normally and issues the fifth prompt message: the power indicator light turns green.

[0059] If the output voltage of the non-rechargeable battery is not greater than the eighth voltage 11.5V and is greater than the second voltage 11.2V, that is, the input voltage of the electric stapler body is not greater than the eighth voltage and is greater than the second voltage, then the control module controls the electric stapler to work normally and issues the fourth prompt message (same as the third prompt message): the power indicator light turns green.

[0060] If the output voltage of the non-rechargeable battery is not greater than the second voltage of 11.2V, that is, the input voltage of the electric stapler body is not greater than the second voltage, then the control module controls the electric stapler to stop working (specifically, to stop firing) and issues a second prompt message: the power indicator light turns red and the buzzer sounds.

[0061] If the health detection of the non-rechargeable battery is abnormal, the control module will control the electric anastomosis device to stop working (specifically, stop firing) and issue a second prompt message: the power indicator light turns red and a buzzer sounds.

[0062] It should be noted that the voltage and power values ​​involved in this embodiment are illustrative and are not intended to limit the scope of protection of this application. In practical applications, the voltage and power values ​​shall be determined according to the specifications of the rechargeable and non-rechargeable batteries and the actual working requirements of the electric anastomosis device.

[0063] In another embodiment of the present invention, an electric stapler is provided. The difference between this embodiment and the previous embodiment is that, after determining that the power supply type is a rechargeable battery, the control module does not control the working state of the electric stapler body based on the input voltage, but rather based on the charge level of the rechargeable battery. In this embodiment, the control module obtains the charge level of the rechargeable battery through a communication interface connected to a fuel gauge, and controls the working state of the electric stapler body in the following manner: If the battery level is not greater than a preset first battery level, the control module controls the electric stapler body to issue the second prompt message and / or stop the electric stapler body from working. If the battery level is greater than a preset first battery level but not greater than a preset second battery level, the control module controls the electric stapler body to work normally and issues the fourth prompt message. If the battery level is greater than the preset second battery level, the control module controls the electric stapler body to work normally and issues the fifth prompt message.

[0064] The electric stapler provided in this embodiment is compatible with both rechargeable and non-rechargeable batteries, but requires the addition of the communication interface accordingly.

[0065] In one embodiment of the present invention, the electric stapler body further includes a display device, specifically a display screen. The display device is electrically connected to the control module, and the control module determines the power level of the power supply and transmits this information to the display device for display. Furthermore, the display device is configured to display the type of the current power supply, for example, by using different symbols or colors to distinguish between rechargeable and non-rechargeable batteries.

[0066] In one embodiment of the present invention, an intelligent power detection method for an electric stapler is provided, applicable to both rechargeable and non-rechargeable battery power detection. The method includes the following steps: The input voltage of the electric stapler is detected, and the power supply type of the electric stapler is determined based on the input voltage. The power supply type includes rechargeable batteries and non-rechargeable batteries. If the input voltage is greater than a preset first voltage, then the power supply type configured in the current electric stapler is determined to be a non-rechargeable battery, and the charge of the non-rechargeable battery is determined according to the input voltage and the initial voltage of the non-rechargeable battery. If the input voltage is not greater than the preset first voltage, then the power supply type configured in the current electric stapler is determined to be a rechargeable battery, and the power of the rechargeable battery is determined according to the output parameters of the rechargeable battery (output data of its internal fuel gauge); The determined power supply type and / or power level will be converted into prompt information and / or display information.

[0067] In this embodiment, the method further includes determining the power supply type of the electric stapler by means of: A discharge module is configured to be electrically connected to the power supply. The discharge module has an operating state or a stopped operating state. The discharge module is controlled to switch from a stopped operating state to an on operating state. If the input voltage decreases, the power supply type is determined to be a non-rechargeable battery; otherwise, the power supply type is determined to be a rechargeable battery.

[0068] It should be noted that the above-described embodiment of the intelligent power detection method for electric staplers and the embodiment of electric staplers compatible with both rechargeable and non-rechargeable batteries belong to the same inventive concept. The entire contents of the embodiment of electric staplers compatible with both rechargeable and non-rechargeable batteries are incorporated into the embodiment of the intelligent power detection method for electric staplers by reference.

[0069] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0070] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
